Definitions

  • This invention relates to refillable reservoirs for marking instruments, especially but not necessarily exclusively for fountain pens.
  • the invention is particularly concerned with so-called fountain pen converters which can be fitted into fountain pens adapted to receive disposable ink cartridges which are replaced when the cartridges are depleted of ink. Converters can be refilled with ink from a bottle of ink.
  • piston rod takes up a relatively large portion of the length of the space available vvithin the pen barrel and therefore restricts the maximum length of the cylinder and hence die volume of the ink chamber within it.
  • a disadvantage of this construction is that the sleeve must be rotated through several revolutions to complete a full axial stroke of the piston, and refilling the reservoir takes a comparatively long time to perform.
  • the sleeve, into which the piston extends when the piston is in its rearmost position still extends a significant distance from the rear end of the cylinder.
  • Another proposal has been to drive a piston by means of an annular magnet surrounding the cylinder, but this would require a large magnet, which in turn would limit the diameter of the cylinder and restrict the volume of the ink chamber if the pen barrel is not to become unduly large.
  • a fountain pen with a barrel enclosing an ink chamber in which a piston is slidable, and a compartment for storing a detachable piston rod which can be inserted through a hole in the end of the barrel and be connected to the piston by a screw-thread when the chamber is to be refilled with ink.
  • a detachable piston rod is inconvenient and carries with it the risk that it will become misplaced or lost.
  • the present invention addresses the above problem and as a solution it provides a refillable reservoir for a marking instrument comprising a cylinder enclosing a reservoir chamber, a piston axially slidable in the cylinder to expel air out of and draw fluid in through the forward end of the cylinder, and a device for actuating the piston having a part extending through a rear part of the cylinder for connection to the piston, the device being movable axially of the cylinder for directly driving the piston and , without becorning detached from d e piston, being positionable substantially within the length of the cylinder when the chamber is filled.
  • a refillable reservoir comprising a cylinder enclosing a reservoir chamber, a piston axially slidable in the cylinder to expel air from and draw fluid into the cylinder through the forward end. and a piston rod protruding through the rear end of the cylinder for displacing the piston, the piston being annular and the piston rod being disengageable from the piston and movable through the piston to allow the piston rod to be disposed in an advanced position in the cylinder while the piston remains retracted.
  • the ability to uncouple the piston rod from the piston means that its projection from the cylinder may be minimal, even with the chamber filled with liquid, and thereby the cylinder can occupy more space within a barrel of the marking instrument and the chamber can have a larger volume for liquid storage.
  • a refillable reservoir comprising a cylinder enclosing a reservoir chamber, a piston axially slidable in die cylinder to expel air from and draw fluid into the chamber, an actuating member movable parallel with the cylinder and alongside the cylinder, and an elongate strip interconnecting the piston and actuating member for me piston to be driven by displacement of the actuating member.
  • the actuating member may be slidingly guided by the cylinder and conveniently it takes the form of a sleeve or collar extending about the cylinder.
  • the strip is suitably a metal or plastic ribbon which can be guided in a longitudinal channel provided on the exterior of the cylinder.
  • the strip is sufficiently flexible to enable it to be bent through 180° between sections of d e strip located inside and outside the chamber, but is also sufficiently strong in tension and longitudinal compression to drive the piston oppositely to the actuating member when the latter is displaced for refilling the reservoir.
  • Figure 1 is an axial section through a fountain pen converter in accordance with the invention and prepared ready to draw in ink to fill the reservoir chamber;
  • Figure 2 shows the converter of Figure 1 in an ink filled condition and housed within the barrel of a fountain pen
  • FIG. 3 is an axial section through another fountain pen converter in accordance with the invention.
  • Figure 4 is a transverse cross-section taken along the line IV-IV in Figure 3;
  • Figure 5 is a partial axial section taken along the line V-V of Figure 3;
  • Figure 6 is an axial section through a modified fountain pen converter of similar construction to that of Figure 3;
  • Figures 7. 8 and 9 are transverse cross-sections respectively taken along the lines VII- VII, VIII- VIII and LX-LX in Figure 6;
  • Figure 10 is a partial axial section taken along the line X-X in Figure 6.
  • the fountain pen converter illustrated in Figures 1 and 2 comprises a cylinder 1 with a main part 2 into the forward end of which is sealingly fitted a connection part 3 defining a spigot for connection to a writing mstniment and having a central port 4 corrimumcating with the ink reservoir chamber 5 enclosed within the cylinder.
  • Slidable axially within the cylinder is an annular piston 6, and extending through the axial opening of the piston is a piston rod 7 which projects dirough the rear end of the cylinder and carries a push-pull button 8 on its outer end.
  • the piston rod conveniently formed from a metal tube, has a coupling member 10.
  • the piston has a frustroconical forward extension 14 which is internally screw-threaded for co ⁇ operation with the coupling member of the piston rod, and the piston carries a seal 15 which seals against both the cylinder 2 and the piston rod 7.
  • the piston rod at all times forms an integral part of the ink converter and it does not become completely detached from the piston. Al ⁇ ough the forward movement of the piston rod through the piston may displace a small portion of ink from the chamber, there is still a large volume of ink retained in the chamber and available for writing with.
  • the piston rod is pulled back and re-engaged with the piston by rotating the piston rod to threadedly connect the coupling member 10 and piston extension 14.
  • the enlarged head 12 of the coupling member prevents the piston rod being withdrawn through the piston.
  • the piston can then be pushed forwardly by means of the button 8 to expel air from the chamber 5 through the port 4 and bring the piston to the forwardmost position illustrated in Figure 1 ready for refilling the reservoir as described above.
  • the piston extension 14 may be split axially to define a pair of jaws which are biased together but which are forced apart by the piston rod as shown in Figure 2.
  • the jaws snap closed around the threaded sections of the coupling member 10.
  • piston rod could have a bayonet type of releasable coupling, or any other form of coupling which can be engaged and released by manipulation of the end of the piston rod.
  • a cylinder 20 having a tubular main body part 21 fitted with a forward end part 22 providing the connection spigot and port 24, and a rear end closure 25.
  • the cylinder encloses an ink reservoir chamber 26. and a piston 27 equipped with an O-ring seal is axially slidable along the cylinder.
  • the axis of the bore through the tubular body part 21 is eccentric so that the wall thickness varies around the circumference as may be best seen in Figure
  • a plastics strap or ribbon 29 which interconnects the piston 27 with an actuating member in the form of a sleeve 30 which is axially slidable along the cylinder.
  • One end of ribbon 29 is attached to the actuating sleeve, e.g. by a peg on the interior of the sleeve being inserted into a hole in the ribbon, and the other end of the ribbon is attached to the piston.
  • the piston is formed of two parts, one part having a peg which projects into a hole in the ribbon and the second part holding the ribbon against separation from the first part.
  • the end enclosure 25 of me cylinder is also formed of two parts or elements securely fixed together, and these two parts define a slot for guiding a portion of the ribbon through a 180° bend, one end of this slot being aligned with the end of the channel 28.
  • the end closure 25 includes an integral button 26 for holding the cylinder during refilling operations.
  • the ribbon 29 is sufficiently flexible to pass around the 180° bend, but is also sufficiently strong and stiff for the piston to be driven to and fro along the cylinder in response to sliding movement of the actuating sleeve 30 back and forth along the cylinder.
  • Figures 6 to 10 illustrate a modified fountain pen converter of the same basic form as that of Figures 3 to 5.
  • the main body part 121 of the cylinder 120 is non-circular in cross section and has a uniform wall thickness, the ribbon guide channel 128 being formed by parallel longitudinal projections.
  • the piston 127 is shaped to fit the bore of the cylinder and like the actuating sleeve 130 is attached to the ribbon 129, in this case a metal strip, as described in connection with the previous embodiment.
  • the rear end closure 125 of the cylinder defines a slot to guide the ribbon through a 180° bend, again as in the previous embodiment.
  • the end closure has a tubular extension which receives and guides an extensible holding button 132 which is normally retracted as indicated in Figure 6.
